Introduction: Improving Efficiency: Relation Orientation & Speed in 3D Printing. I Made It at TechShop.

Picture of Improving Efficiency: Relation Orientation & Speed in 3D Printing.  I Made It at TechShop.

Background:
     There are many way to speed up 3D Printing.   One is to make percent fill less.  Normally, users don't use 100% fill.  Normally, they range from 10% to 50%.   However, in some applications changing of percent fill might not be an option.  Or we keep everything the same, what else is possible to speed up the 3D printing.

Goal:
      To verify an hypothesis on improving 3D printing speed.   To measure the speed up based on a simple shape.

Discussion:
       The hypothesis is not meant to include all possible shapes.  If a part is largely rectangular, having one motor move from left to right of the bed might be slower to go from one end to another.   If we place a part at 45-deg, how much speed up could we gain?
       A cylindrical or flower base shape would likely not have any significant effect.
       During our discussion, my friend at TechShop brought out a good point.  What if the extruder speed is the critical factor?  This could be very true.
       So to quickly check out this hypothesis, I decided to conduct a test. 

        If anyone know other related study, please share.  Thank you very much.

        My test samples would 5" long x 1" width x 0.25" thickness.  Due to limited material, I could only use 10% fill.and run maximum 6 tests.  10% is most common used so I think it is best to use this.  I would rotate the part 45-deg along the vertical.  I would also rotate it about the X + 45-deg about the vertical.

         Due to limited time on  3D Printer at the Shop, I would gradually update the result. I am updating the 6 alignment configuration..   In Autodesk, we only need to make 1 file.  The rotation could be done on MakerBot. 
Configurations are the following:  
    (1) 5" along X   
    (2) 5" along X sideway
    (3) 5" along Y
    (4) 5" along Y sideway
    (5) 45-deg
    (6) 45-deg sideway

Conclusion:
       Since the test is very simplified.  No conclusion could be derived from the above exercise.  Only conclusion could be if the orientation affect the printing speed.

DIsclaimer:
       This test is based on simple shape and 10% filled.  This test is based only on one simple case.  No generation should be derived from it without conducting a well planned DOE.
        I did not try to search if this test has been done in the past and analyze all factors in depth.  I simply conduct this simple and likely unscientific tests.
